Answer 1

As I said in another answer, I found this to be a good way: PNG Animation method by Moses DeJong

From his words:

This example implements an animation oriented view controller that simply waits to read the PNG image data for a frame until it is needed. Instead of alllocating many megabytes, this class run in about a half a meg of memory with about a 5-10% CPU utilization on a 2nd gen iPhone.

I'm still unsure exactly how it's done. I believe it basically uses UIImageView to cache up AVAudioPlayer.
